MITER-BOX.

Application filed August 3, 1916.

To all 'whom t may concern:

Be it known that I, ARTHUR J. HELMs, a citizen of the United States,residing in the city of Portland, county of Multnomah, and State ofOregon, have invented certain new and useful Improvements in Miter-Boxes, of which the following is a specification.

My invention relates to miter boxes and has among its salient'objects:to provide in combination with a body, a pair of adjustable saw guidesfor holding a saw in a vertical plane for operation horizontally, or foroperation in an inclined position between the horizontal and thevertical, which saw guides are adjustable bodily toward and from eachother at opposite sides of the piece being sawed, whereby to assist inholding the piece `being sawed during the sawing operation; to providein combination with the body of said device an adjustable support forthe piece to be sawed, which support is pivoted to turn upon a verticalaXis, whereby to hold the piece to be sawed at any adjustable angle in ahorizontal plane; to provide a two-part adjustable support, one part ofwhich is adjustable relative to the other part about its longitudinalaxis to di'erent angles, whereby to make possible the cutting of a pieceof wood on a compound angle; to provide a device `which can be collapsedand folded together, whereby to occupy asmall compass when not in use;and, in general, to provide a simple and practical miter box of thecharacter rei'erred to.

In order that others may understand my invention, I have illustrated onepractical embodiment thereof in the accompanying` sheet of drawings,which I will now describe.

Figure `l is a top plan view thereof;

Fig. 2 is a side elevation of the device with a part shown in section online 2--2 of F ig. 1;

Fig. 3 is an end view looking at the right hand end of Fig. 1, with thesaw indicated in light dotted lines; and

Fig. 4 is an end view, looking at the lefthand end of Fig. 2.

Referring now more in detail to the drawings, my invention comprises abody 1, preterably composed of two spaced members 1'a and l", withspacing pieces 2-2, at their opposite ends. Slidably mounted betweenSpeccation of Letters Patent.

Serial No. 112,980.

said parts 12L and lb, at opposite ends, are

`two pairs of guide members 3-3, with a connecting bolt 4, for eachpair, provided with a thumb-nut 5, for tightening said guide members3-3, in whatever positions toward and from each other they may beadjusted. Secured to the outer ends of said bolts 4-4, are guide pieces6 6, the heads of the bolts 4, being `countersunk in the outer sides ofsaid guide pieces 6-6, as clearly indicated in dotted lines, said guidepieces being adapted to turn upon said bolt, whereby to be adjusted toany positions around said bolts.

Slidably mounted upon each of said guide pieces G-6, is a saw guide 7,having a projecting guide 8, attached at its upper end and spaced fromthe body of said guide 7, to form a slideway 9, open at its "lower end,for the saw. As the guide pieces 6--6, can be turnedupon the bolts 4-4,it will be evident that the saw `can be operated by a straighthorizontal movement, or that it can be operated on an incline, with thepoint of the saw directed downwardly, as indicated in Fig. 3. i

Pivotally mounted upon the body l, is a support 10, said support beingprovided at its attached end with a round portion 11, set into acorresponding socket 12, formed in the upper side of the body l, asclearly shown in F ig. 2. The attached end of said support is rounded,as at 10, and a scale 10b, is provided to determine its position ofadjustment relative to the body 1.

In order to lock said supporting member 10, in adjusted positions, it isprovided in its rounded edge with a groove 13, in which fits a nut 14,attached to a. thumb screw 15, which can be set so as to lock saidsupport in adjusted positions. Hinged to one side of said support 10, isan adjustable part 16. which can be let down into the same plane withthe part 10, or can be adjusted to an angle relative to the saine, asshown in Fig. 4, said part 16, being provided with aholding bar 17,provided with a thumbscrew 1S, adapted to move in a curved slot 19, in asegment 20, provided with graduations, as at 21. The end of the bar 17,is pointed, as at 22, to indicate the angle. The adjustable member 16,is beveled at its inner end so as to give clearance when said support10, is turned upon its pivotal attachment to the body l, toward the topin Fig. 2. Thus it will be seen that amolding, or other piece of wood,can be sawed Lsquare off on any angle by resting it fiat-wise upon thesupport 10, and project-ing it into the path of the saw, or it can besawed on acompound angle by being held up against the part 16, which canbe adjusted relative to the body 1 with the piece to be sawed projectinginto the path of the saw.

A pivoted extension piece 23, may be attached, as at 24, to the beveledend of the member 16, as shown, to be moved out at will to form acontinuation of said member 16, at its beveled end, when needed, saidpiece 23, being of the same thickness as said member 16, and having athin segmental portion 25, which telescopes into the end of said member16, as indicated in dotted lines, said thin portion being provided witha curved slot 26, through which a stop pin 27 projects.

I am aware that changes can be made in ,my invention as here illustratedwithout departing from the spirit thereof, and do not, therefore, limitsaid invention to the particular showing here made, except asc may belimited by the hereto appended claims.

I claim:

1. A miter device of the character referred to comprising in combinationa body, two vertical saw guides adjustable toward and from eachotherlongitudinally along said body, a supporting member pivotally connectedat its end to said body between its ends and adapted to be adjusted todifferent angles in a horizontal plane relative to said body, saidsupporting member also having a portion adjustable about an axisextending longitudinally thereof, whereby to turn the piece to be sawedabout an axis extending longitudinally thereof.

2. A miter box of the character. referred to comprising in combination abody, two vertically disposed guide pieces adjustably and pivotallyconnected to said body and adjustable both pivotally and bodily towardand from each other longitudinally along said body, saw guides slidablyconnected with said guide pieces and adapted to receive a saw blade, asupporting member adjustably attached at its end to said body betweenits ends and adapted to hold the piece to be sawed at different anglesin a orizon Va .1 anc h tal pl ne, cross wise of sa d body l yin thepath of said saw, substantially as described.
